Maintenance Manual E-mail Pre Ride inspection The more care and maintenance you give a bike the longer it will last. Performing inspection and general maintenance regularly on your motorcycle will also help you spot problems before they happen. Even doing a little can make a big difference. Therefore, it's advisable to inspect your motorcycle everyday before you go for a ride. The following checks in the long run can save time, expense and possibly avoid any fatality: . Â Â Â Engine oil level - Add engine oil if required. Checked visually for any leakage. . Â Â Â Fuel Level - Fill the fuel tank when necessary. Check for any leakage. . Â Â Â Front & rear brakes - Check the braking operation and adjust free play if necessary. . Â Â Â Tires - Check condition & pressure. . Â Â Â Drive chain - Check condition & slackness. Adjust & lubricate if necessary. . Â Â Â Throttle - Cable inspection & adjustment. . Â Â Â Lights & Horn - Check the headlight, tail/stop light, turn signals, indicators & horn function properly. Correct any discrepancy before you ride. Contact your nearest authorized Demak dealer for assistance if you cannot correct the problem. Engine Oil Engine oil is a key determinant for efficient motorcycle performance and increased engine life. Regular oil and filter changes will keep your motorbike young and healthy. Make sure you regularly check and keep your oil level at its HIGH or MAX level. It is best to check your oil level on the bikes centre stand or when it is in a level position. An under filled oil level can be disastrous while too much oil over the limit may flood your air cleaner with oil. Here are some pointers regarding oil: . Â Â Â The bike should be level as possible. . Â Â Â The oil should best inspected cold and is therefore best done before you go out on a ride. . Â Â Â Be careful to not allow foreign matter and dirt to fall in during the inspection process. . Â Â Â With threaded dipsticks do not screw the dipstick in when taking a reading, just allow it to rest on the lowest thread. . Â Â Â High temperatures, time, speed, heavy traffic, short trips and dust quickly destroy the quality of your oil. If you do ride in these conditions change your oil more frequently. . Â Â Â It is recommended changing your oil every 2-4000km or 3-6 months, whichever comes first. . Â Â Â It is recommended you change your oil filter every other oil changes if you are using a good quality oil filter. If not, every oil change. For best result from your Demak motorcycle we recommend to use Sprinta Petronas. Brakes Motorcycles have brake fluid reservoir which usually found on the handlebars. It should be checked regularly. Topping up should only be done from a new, sealed bottle as brake fluid tends to absorb moisture over time. If your brake pads are thin and due for replacement, do not top up the reservoir - replace the pads first and the level in the reservoir will rise automatically. Also check the thickness of the brake pads. If you allow them to go right down to the metal your brake disc will be damaged resulting in an unnecessary and expensive replacement. Fitting braided steel brake lines will increase the performance of your brakes by roughly 50%. Here the thickness of the brake pad can be seen. It clearly has a lot of mileage to offer before needing to be replaced. If your bike is used off road or is exposed to corrosive forces ensure that the pistons that force the pads onto the disk are cleaned and serviced once a year. Chain and sprockets, Shaft Drives, Belts These items that is essential to the well being of your bike. Chains: Lubricate them often with a commercial chain spray everytime you fill up for gas. (or at the end of each ride). Spray liberally on the side of the chain that comes into contact with the sprockets. Ensure that you spray both left and the right hand side of the chain. Position a piece of newspaper so that you do not dirty the rear wheel rim as you spray. Use a second piece on the floor to catch any drips. Wait five or ten minutes before you wipe all excess oil off the chain. Spinning the back tires will ensure that the rest of the chain is lubricated when it comes into contact with the sprocket and pinion. This is a task that is best done when you return home from your ride while the chain is still warm. Bike chains are never taut but must be able to sag between 20mm and 40mm at the mid-point between the two sprockets. The sag is used when the bike suspension moves up and down over uneven surfaces If your chain becomes very dirty e.g. after a long ride on a dirt road, leave it overnight. The crud becomes hard and is easily brushed off with a small steel wire brush the next morning. If you do want to clean it with a solvent do not use petrol as this dries out the small rubber O rings in the chain. Use a commercial chain cleaner, kerosene or diesel fuel as these are all oil based. Chains stretch with time no matter how well they are cared for. You will know when the chain has stretched too much when you are able to pull the chain off the back of the rear sprocket. See diagram below: When you try this when the chain is new, it will not budge from the sprocket but when it has become stretched, it moves off easily. Shaft Drives: Even though shaft drives on motorcycles require little maintenance we would suggest replacing the shaft drive oil every 1 year. This will lead to a very long and happy life for the shaft drive. Belt Drives: As with shaft drives, belts do not require a lot of maintenance. Everytime you change the oil on your motorcycle check the belt tension and adjust if necessary. Make sure your belt is always clean. Tires Keep your tires correctly inflated. A tire that is very under-inflated generates a lot of heat which can lead to a blow out. Tires that run too hot also wear out more quickly. The most common motorcycle breakdown is for tire damage. Replace your tires sooner rather than later. If tread depth is 1-2mm it is time to replace your tires. Battery Your motorcycle battery needs periodical maintenance to ensure a long and trouble free life. A battery only requires a little monthly maintenance to perform perfectly. Keep the battery charged to 100%, recharging when the lights dim, the starter sounds weak, or the battery hasn't been used in more than two weeks. Other than that, follow this simple check list every month: . Â Â Â Check the electrolyte level . Â Â Â Top up only with distilled or deionized water, wear gloves and protective glasses. . Â Â Â Top up in a well ventilated area, Beware of fumes. . Â Â Â Keep the top free of grime . Â Â Â Check cables, clamps, and case for obvious damage or loose connections . Â Â Â Clean terminals and connectors as necessary . Â Â Â Check inside for excessive sediment, sulfation or mossing . Â Â Â Make sure the exhaust tube is free of kinks and clogs . Â Â Â Replace caps firmly . Â Â Â Finish up by testing the battery with either a hydrometer or voltmeter. To extend the service life of your battery, make monthly battery maintenance part of your routine. Wiring It is a fact that the electrical systems on motorcycles are more prone to giving problems than any other single sub system. Therefore make it a routine when giving your bike a through cleaning to check for loose and frayed wires that can cause intermittent problems or short circuits. Riding Motorcycle's Do's and Don't's DO's . Â Â Â Drive at steady speed . Â Â Â Maintain correct tires pressure . Â Â Â Adjust drive chain tension correctly . Â Â Â Get your engine tuned & motorcycle serviced regularly by the authorized dealer DONT's *Â Â Â Â Do not keep the clutch lever pressed while riding *Â Â Â Â Do not run the engine in low gear for long time *Â Â Â Â Do not keep brake pedal pressed while riding *Â Â Â Â Do not raise engine rpm during traffic halts *Â Â Â Â Do not cover Inlet of Air Filter assembly *Â Â Â Â Do not cover the engine in the front and side. (This may restrict the smooth air flow to the engine fins required for air cooling and the engine may run at a higher temperature) Motorcycles which do not undergo a periodic maintenance are liable to emit exhaust gases more than the permissible limit. Some of the tips to maintain the low emission level are: . Â Â Â Spark plug should be cleaned and specified gap should be maintained between electrodes . Â Â Â Keep the air filter clean . Â Â Â Get the carburetor tuned at authorized workshop . Â Â Â Do not overfill the engine oil and get it replaced as scheduled . Â Â Â Avoid use of adulterated fuel
